DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The following part will illustrate exemplary embodiments of the present disclosure with reference to the drawings, including various details of the embodiments of the present disclosure for a better understanding. The embodiments should be regarded only as exemplary ones. Therefore, those skilled in the art should appreciate that various changes or modifications can be made with respect to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for clarity and conciseness, the descriptions of the known functions and structures are omitted in the descriptions below.

In addition, it should be understood that the term “and/or” only describes an association relationship between associated objects, and indicates that three relationships may exist. For example, A and/or B may indicate three cases: only A exists; both A and B exist; and only B exists. In addition, in this specification, the symbol “/” generally indicates that associated objects have a relationship of “or”.

FIG. 1 is a flow chart of a method for regression test according to a first embodiment of the present disclosure. As shown in FIG. 1 , the method includes the following implementation steps of:

Step 101: when execution of any regression test is completed, determining a to-be-adjusted test case from test cases according to a current test result; and

Step 102: adjusting a randomization weight corresponding to a data range randomized by the to-be-adjusted test case in a current test.

It is observed that in the solution of the above method embodiment, an adaptive-adjustment regression test method is adopted, such that a data randomization direction of a subsequent regression test may be adjusted according to the test result of the performed regression test, thereby improving test efficiency, or the like.

In practical applications, usually, plural regression tests are performed on a tested object until an end condition is met, for example, a predetermined code coverage rate requirement is met.

In the solution of the present disclosure, when the execution of any regression test is completed, the to-be-adjusted test case may be determined from the test cases according to the current test result. The current test refers to a most recently executed regression test.

In one embodiment of the present disclosure, the to-be-adjusted test case may include a positive to-be-adjusted test case, and correspondingly, the step of determining a positive to-be-adjusted test case from test cases according to a current test result may include: for any test case with a current test result of pass, if test results of the test case in continuous M tests including the current test are determined to be pass, using the test case as the positive to-be-adjusted test case, M being a positive integer.

All test cases may be used for each regression test, and the test result of each test case is either pass or fail.

A specific value of M may be determined according to actual requirements, and may be 1, or greater than 1. If the value of M is 1, if the current test result of any test case is pass, the test case may be taken as a positive to-be-adjusted test case; if the value of M is greater than 1, and is assumed to be 3, when test results of the test case in the current test and two tests before the current test are pass, the test case may be taken as a positive to-be-adjusted test case. The specific way may be determined according to actual requirements, which is quite flexible and convenient.

A randomization weight corresponding to a data range randomized by any positive to-be-adjusted test case in the current test may be adjusted, and in one embodiment of the present disclosure, the randomization weight corresponding to the data range randomized by the positive to-be-adjusted test case in the current test may be reduced, and randomization weights corresponding to other data ranges may be unchanged.

Usually, the higher the randomization weight is, the greater the randomized probability is, and conversely, the smaller the randomized probability is, and therefore, by reducing the randomization weight corresponding to the data range randomized by the positive to-be-adjusted test case in the current test, and other data ranges may be randomized as far as possible during a next test, so as to realize a fast increase of the code coverage rate, i.e., an improvement of the test efficiency, or the like.

For each test case, during initialization, i.e., before a first regression test is performed, an initial randomization weight may be set; for example, the randomization weights corresponding to different data ranges may be set to be the same; that is, case data is completely random within a required range; a local key test may also be supported; that is, during initialization, a randomization weight different from other randomization weights may be set for a specific data range, and a specific implementation is not limited.

In one embodiment of the present disclosure, for any positive to-be-adjusted test case, a current adjustment value may be determined first, and then, the adjustment value may be subtracted from the randomization weight currently corresponding to the data range randomized by the positive to-be-adjusted test case in the current test, thereby obtaining a reduced randomization weight.

In one embodiment of the present disclosure, a preset adjustment step may be used as the adjustment value, or the adjustment value may be determined in conjunction with the adjustment step and a preset rule. That is, the solution according to the present disclosure supports different adjustment value determination manners, which is quite flexible and convenient.

A specific value of the adjustment step may be determined according to actual requirements, and may be modified/adjusted at any time according to actual requirements after set.

Correspondingly, during determination of the adjustment value, a current adjustment step may be used as the adjustment value directly, or the adjustment value may be determined in conjunction with the current adjustment step and the preset rule, and the specific rule is not limited, and may also be determined according to actual requirements; for example, a product of M and the adjustment step may be used as the adjustment value.

In one embodiment of the present disclosure, the to-be-adjusted test case may also include a negative to-be-adjusted test case, and correspondingly, the step of determining a negative to-be-adjusted test case from test cases according to a current test result may include: using a test case with the current test result of fail as the negative to-be-adjusted test case.

A randomization weight corresponding to a data range randomized by any negative to-be-adjusted test case in the current test may be adjusted, and in one embodiment of the present disclosure, the randomization weight corresponding to the data range randomized by the negative to-be-adjusted test case in the current test may be increased, and randomization weights corresponding to other data ranges may be unchanged.

By increasing the randomization weight corresponding to the data range randomized by the negative to-be-adjusted test case in the current test, the data range may be randomized as far as possible during a next test, so as to realize a key test, or the like, near an error region.

In one embodiment of the present disclosure, for any negative to-be-adjusted test case, a current adjustment value may be determined first, and then, the adjustment value may be added to the randomization weight currently corresponding to the data range randomized by the negative to-be-adjusted test case in the current test, thereby obtaining an increased randomization weight.

In one embodiment of the present disclosure, a preset adjustment step may be used as the adjustment value, or the adjustment value may be determined in conjunction with the adjustment step and a preset rule.

A specific value of the adjustment step may be determined according to actual requirements, and may be modified/adjusted at any time according to actual requirements after set.

Correspondingly, during determination of the adjustment value, a current adjustment step may be used as the adjustment value directly, or the adjustment value may be determined in conjunction with the current adjustment step and the preset rule, and the specific rule is not limited.

Based on the above-mentioned description, FIG. 2 is a flow chart of a method for regression test according to a second embodiment of the present disclosure. As shown in FIG. 2 , the method includes the following implementation steps of:

Step 201: performing a first regression test.

For each test case, an initial randomization weight may be set during initialization.

Step 202: determining whether a predetermined code coverage rate requirement is met, if yes, ending the process, and if no, executing Step 203.

Step 203: processing each test case in manners shown in Step 204 to Step 206.

Step 204: determining whether a test result of the test case is pass or fail, and if the test result is pass, executing Step 205, and if the test result is fail, executing Step 206.

Step 205: taking the test case as a positive to-be-adjusted test case, reducing a randomization weight corresponding to a data range randomized by the positive to-be-adjusted test case in a current test, and then, executing Step 207.

For example, a current adjustment value may be determined first, and then, the adjustment value may be subtracted from the randomization weight currently corresponding to the data range randomized by the positive to-be-adjusted test case in the current test, thereby obtaining a reduced randomization weight.

A preset adjustment step may be used as the adjustment value, or the adjustment value may be determined in conjunction with the adjustment step and a preset rule.

Assuming that the adjustment step is used as the adjustment value directly, a difference between the randomization weight before adjustment (the currently corresponding randomization weight) and the adjustment value may be calculated, and a calculation result is used as the adjusted randomization weight, i.e., the reduced randomization weight.

In addition, it is observed that a value of M is assumed to be 1 in the present embodiment.

Step 206: taking the test case as a negative to-be-adjusted test case, increasing a randomization weight corresponding to a data range randomized by the negative to-be-adjusted test case in a current test, and then, executing Step 207.

For example, a current adjustment value may be determined first, and then, the adjustment value may be added to the randomization weight currently corresponding to the data range randomized by the negative to-be-adjusted test case in the current test, thereby obtaining an increased randomization weight.

A preset adjustment step may be used as the adjustment value, or the adjustment value may be determined in conjunction with the adjustment step and a preset rule.

Assuming that the adjustment step is used as the adjustment value directly, a sum between the randomization weight before adjustment and the adjustment value may be calculated, and a calculation result is used as the adjusted randomization weight, i.e., the increased randomization weight.

Step 207: after all the test cases are processed in the above manners, performing a next regression test, and then, repeating Step 202.

A method of performing the regression test belongs to a prior art.

All test cases may be used for each regression test, and the test result of each test case is either pass or fail.

A specific value of M may be determined according to actual requirements, and may be 1, or greater than 1. If the value of M is 1, if the current test result of any test case is pass, the test case may be taken as a positive to-be-adjusted test case; if the value of M is greater than 1, and is assumed to be 3, when test results of the test case in the current test and two tests before the current test are pass, the test case may be taken as a positive to-be-adjusted test case.
